I need to do something similiar and I am stumped as to how to accomplish it. Here's the scenario.. users are in my website, they click on something say reservation for example then they click on ? to get help, my ? redirects them to a support website which contains site specific information and resources, one of those resources is the helpfile, I need to map into the helpfile depending on what is returned into the help system via the query string, specifically I need to set iframe src= to that portion of the helpfile. I thought it would be easisest to do this using a hash, so I setup a hash with the key topic and the value=to the url I want to insert as content into the helpframe, with the src equal to that location the target should be the iframe for each src, I cannot for the life of me figure out how to pass the info into my file. my file is asp..and I have my hash but I cannot figure how to match my topic with the topic keys and then return the value, then aftewards set the iframe src to it.. its baffling the almighty h out of me. can you help?
